Recently I've seen alot of threads where people just jump into writing an incredible episode without putting their readers into consideration.
I'm not a fan of reading very long articles and most times I think some posts ought to be simplified and summarized to get ease of attention and from my observation, it seems most users confuse quantity with quality and think, writing very long post simply means the post has quality which is wrong.
I've seen very short and straight to the point post doing extremely very well on the forum and people ought to them learn from them.
However, not all topics need to be short and precise as there are broad topics that need to be explained well and it can only be possible by making a long post so that all the important details will be listed there. That's up to the readers if they can't still get the main content of the post. As long as you never miss all the important factors, I believe that post is still a quality post.
